To all 'whom 'itmy concern."

Bc it known that il, MAX GINsBUnG, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in I-nterchangeable Letter-Embossing Dies, of which the following is a specification.

My invention relates to embossing meehanism, and particularly to a mechanism for lein bossing and forming sheet metal signs, the

-ohject of my invention being to rovide einhossing dies having interchanges le elements capable of heiner quickly removed, cihanrfed' or transposed, t ius`allo wing Ithe various etters or c laraoter units forming the die for one sign, to be quickly changed and reset-up to form a-die for embossing another sign.`

To this end my invention consists in the an-rangement of parts 'and detailof construe` tion as shown in the aocornpan ing drawings and seft forth in the appendeddiaims.

In the drawings Figure 1, is a erspective View of one half of my die. IPig. 2, is a transverse section on the line :tr Fig. 3, is a pers ective view of the other al-f ofthe die with t e s )acng blocks removed in order to more clear y show `the construction. Fig. 4, is a transverse section on the line z-z of Fig. 3; Figs. 5 and 6, are perspective views ofthe male and female units respec.

tively, and Fig?, is a perspective of a corner of one oi the inner frames, Fig. 8, is a perpective view of vone of the small spacing ocks. Like reference characters throughout the .everal views designate like parts.

A desi nates an exterior frame or chase within w ich is mounted an interior letter carrying frame B. Both of these frames are 'shown as square in plan, lthough 'they ohviously may be made of any other rectangu-V lar ligure. one for the 45' There are two of these chases,- d. male and the other for the female fie. i

The -frarne Ais adapted vto he placed in and4 attached .to any suitable embossing press, and it is rovided on its sides with the set screws A', aving heads a and the nuts-athe shanks of the set screws passing tln'ou h the sides of the frame and `provided insi e the frame with the nuts a2 whereby the set screws may be clamped and held in any suitable position. It will be seen from Fi s. 2 and 4 that the frames are each provir ed with a solid bottom plate A2.

The. frame B is smaller than 'the frame A, has -no bottom fplate, amd is adapted to be set within the frame A. The set screws A will engage with the sides of this frame, and by adjusting the set screws relatively to eac other the internal traine B m ay yhe adjusted to its proper central position with reference to the frame or chase A and he rigidly held therein. The frames B are a'like for `both the tion of one will apply quite ascorrectly to t e other.

The fram-c B is formed of two side pieces i) and -two end pieces b', .the side pieces b. roject over the ,end -pieces b in order to orrn the joint at t'he corners ofthe frame, and bhe end pieces b. are provided at their extremitiesrwith die portions fb whereby an ornamental corner will be -rnade at the corner of the frame. Both the side and :end pieces are formed wit-h ya marginal flange b3, in`t'he frame -fonming part of the femae die which fits down over tfhe outside of the male die Vfra-me. It is ofcourse, tobe understood that the frame forming the male die is rovided with projections at the 4corners of t e frame, and Vthe female die with recesses as shown -in Figs. 1 and 3. I have shown the face `of the side and end pieces plain, but it is to #be undermental character desired, so as tb impress ah erna-mental border around the margin of the sheet metal sign made thereby. y

'In order to sup ort the sp'aoin blocks and letter iblocks witliin the frame.' Il provide the transverse Wires D which pass lthrough a series of perforationsd in the side -franles 'l1 and project out on both sides oi the fra-me. 'Ihese wires are of a strong and rigid charac- A-ter and Acarry on their ends, the lrwing nuts and washers There may lbe as man .of these wires ashrlesiredbut they shoul evenl spaced apart. I have found by pmetice t iat a distance of one inch is a convenient spacing distance for these Wires.

' 'lhe end pieces are also formed with passages or perforations d and the wires D may be strung between the `end pieces 1J in laoe of 'betwcenthe side pieces Il). These ro s not only tact to sup o blocks as hen-nadie:` described, hut they also act to hold the sides and ends of thc frame B tightly together. It will be understood of course, that l may use any further means of joining rigidly the sides and end ieces and in this connection I prefer to use t 1e dowels E stood that they may hemade ofany ornaf/ rt the letter and spacing- Amale and female dies and hence the dcsori in the end ieces entering the dowel opening e in the si e pieces as shown in Fig. 7,

.The letter blocks F, and spacing blocl'gs F', F, Fa are formed of any desired size and are rectanular in plan, s that the several blockssha lit closel togo lier whenl mounted Within the frame Each block has passages fthrough it, these passages being the, saine distance a art as are the wires D.

In the large etter blocks F as shown in Fig. 3, there will be two or three passages f passing transversely through them, while i ongitudinally there Will be at least two passages in the larger blocks. These passages are preferably an inch apart and I prefer to use this unit throu h m construction. The blocks are multip es o each other, so that the shall t to ether as shown in Fig. 1, severa small bloc occupying the place of one' large block if desired.

preferably use three sizes of blocks, the

. largest F, F', bein the let-ter blocks and the y use smaller blocks for the subordinate lar e spacing blorl s, the'next size F2 acting as llers and the smaller size F3 which are preferably one inch square being used around the margins of the frame. These blocks owever, i nay be laced in any position desired in order to l up the s ace vvithin the frame and hold the letter bloc s rigidly in position, so that the cannot slip from one side to the other, and sothat a smooth background will be formed for the die.

While I have shown the letter blocks as bting of the largest size, l ofcourse do not irish to limit myself in this regard as I may also ottering. lt will of course be understood that the letter blocks on the male dic have the letters raised thereon, and that on the female die the letters are correspondingly depressed.

By providing the bloc s with passages f running in opposite directions I ain enabled to set the letter blocks in any position desired within the chase. The construction enables the removal of any of these blocks and the substitution of others or permits rcarrangin4 the blocks in any esired manner by siinp y unscrewin the nuts on the rods D removing the bloc s and replacing them with others, of course changing the s acing blocks to correspond. The nuts are t en replacedupon the rods l), the form is locked and placed within the chase A and locked iii lace therein by the marginal set screws A'.

It will be seen that when locked in place the blocks are backed by the bottom or top plates A of the male or female chase, that they are rigidly held against anylateral movement, not only by the tension of the wires D but by the spacing blocks, and that the wires `venti g them from 'any suitable embossing l) hdld't-hc blocks in osition, ositively )ro- )eing shi ted or telling out o the chase.

lp operation a sheet of metal of suitable thickness is place-d between the male and female members of tho die uhich are held in rose andthe mombers ressed together \.\l)icroupon the sheet nieta is ciiibosscd according to tho letters or other elements supported within the frana'. f While l intend my dcviei` to hc particularly used `for embossing lettered signs, it `maj,r also be used for moro ornamental signs wherein the units or elements lf, ll", l ".may be of an ornamental character riitirrly. Ul' course,l may use those ornamputul units iii conjunction y, ith the lotti-r units and the s acing units before described. By moans o my invention l am enabled to srt up tho embossing units of shoot metal signs roi-y quickly and to impress these signs at short notice and in a manner u hivh has boi-n impossible heretofore.

Having thus described my invention u hat l claim as non" aud desire to secure by Lit ters Patent is:

1. An embossing die including a frame formed of side and end pinces provided vith a series of transverse iros having tightening moans on their ends, and embossing units` and spacing blocks shiltably mounted upon said hires and removable therefrom.

2. An embossing die including male and feiiiale die frames, cach frame composed of sido and end pieces, said frames bring formed on their faces v ith malo and female embossing piojictions and recesses, a .serios ol' iros passing across said frames having' nuts on opposite ends of each wire 'ehorili f th(` soctioiis of tho frame may be hold rigidly together, and letter blocks having passagvs through which the vil-ospass, said blocks having male and femalel faros, spacing hlm-hs also formed 'a ith )assages for said u iros aud ada t'ed to be placed around tho said lio bloc rs, and a chase into hich said diil carrying frame is set, said chase having a lacking against which thc dio units are supported, and moans on the margins ol' tlm chase lor locking the chase in place, and adjusting thi` frame and the chas-c ith relation to cach other.

lnvtestiniony .vhcroof l have siugod my name to this speeir'atioii in tho presence of two subscril'iiug a itiiessos.
